OlLED-ROAD ROLLER, KNEADER, AND PACKER- Specification of Letters Patent.

Patented. Aug. 1, 1905.

Application filed May 28, 1904. Serial No. 210,180.

To all whom, it may concern:

Be it known that I, ALFRED E. BURNS, a citizen of the United States, residing at Los Angeles, in the county'of Los Angeles and State of California, have invented a new and useful 'Oiled Road Roller, Kneader, and

Packer, of which the following is a specification.

- The main object of this invention is to provide superior means for incorporating or mixing oil with the superficial material of a road.

The invention comprises a machine which is intended to be used in conjunction with or subsequently to the application of ,oil to the road, and is adapted to stir or turn over, knead, and mix the oil and loose material on the road-surface, so that the oil which has been applied will be evenly distributed and incorporated with the loose surface material or dust.

, A further object is to provide a machine which is particularly adapted to knead and pack the loose earthy matter and oil when oiled roads are constructed by loosening up the earthy portions of the road and incorporating heavy asphaltum-oil therewith and suitably packing the same.

The oil-incorporating means comprises a plurality of wheels rotatably connected to a traction-frame and adapted to be drawn over the surface of the road, said wheels being sufficiently separated to allow each wheel to penetrate slightly into the loose material on the road and by its rotation to displace and mix the material.

In connection with such a machine an obect of my invention is to provide means whereby the wheels will be kept clean of the oil and road material and the dust and oil will be kept away from the bearings of the wheels.

An additional object of the invention is to make such cleaning means adjustable and removable. v g

A further object of the invention is to provide for smoothing and packing. the superficial road material after the incorporation of oil therewith. The effect of the wheels above described is to form longitudinal furrows and ridges in the road, and I provide means for smoothing out these inequalities and at the same time packing the mixture of oil and dust into a firm coherent mass, making a roadsurface ready for use. 1

The accompanying drawings illustrate the invention.

a plan with a part of a spring device connect- Fig. 4: is

ing the roller-frame with a draft device,'partly broken away. Fig. 5 is a detail of a fastening device for the wheel-cleaning means.

The roller means consist of a plurality of parallel flat-tread wheels-1, rotatably mounted on a shaft or axle 2, the said wheels being longitudinally strung along said shaft in such manner that the periphery or rim of each wheel will be separated from the rims of the adjacent wheels. secured in a traction-frame 3, which may be provided with any suitable draft meansfor example, an attaching meanswhereby it may be connected to adraft-truck 4, said attaching means comprising, for example, a hook 5 and a spring-and-chain connection 6.

7 designates the drivers seat, which may be on the forward end of frame 3.

The roller-wheels 1 are adapted to run on the surface of the road and to support the shaft 2 and the frame 3. In order to cause said Wheels to bear with suflicient pressure on the surface of the road, means are provided for weighting the frame, said means thereof, which are connected in suitable manner to the frame 3. I prefer to make such connection adjustable, the bars 13 being clamped to the rear standards 9 by adjustable clamping means, comprising a clevis or yoke 14, formed in U shape and screw-threaded at each end to receive nuts 15, and a bar or crossplate 16. engaging and extending between the 'two bars of said yoke andbeing ad usted thereon by said nuts. In applying the clamp- Said shaft 2 is mounted or ing device the U-shaped yoke is placed over a standard 9, so as to embrace the same, and the cross-plate 16 is then engaged with the yoke and held thereon by the nuts 15. The scraper-carrying arm or bar 13 having been inserted between said cross-plate and the standard the said cross plate is clamped thereon by screwing up the nuts 15, so as to hold said bar and the scraper firmly in position. On releasing said nuts the clampingyoke may be slid up or down on the standard and the scraper-carrying arm may be slid longitudinally between the crbss-plate and the standard, so that the scraper can be adjusted both vertically and horizontally or, in respect to the wheel, both cireumferentially and radially.

Scraper-bar 12 is preferably, for the sake of stiffness, a bar of angle-iron, and to enable reversibility of said bar the limbs or arms are at right angles to each other and of substantially the same width, and each one is provided with holes 17 for the reception of bolts 18, whereby it is fastened to the arms 13. When one edge or limb of the bar 12 is worn out by abrasion of the wheels thereon, the angle-iron is unbolted, turned to present its other edge to the wheels, and bolted by the last-named edge to the carrying-arms.

The scraper 12 by its location and also by reason of its downwardly-extending limb or edge will substantially prevent the mixture of oil and dust from being carried up over the wheels and dropped on the hubs and axle; but as some will adhere to the edges of the rim-wheels and may fall on the hubs I provide guards between adjacent wheels, said guards consisting of rings 20, surrounding the hubs 21 of the wheels. When the hubs are spaced apart on the axle, washers 22 may be interposed between adjacent hubs within the rings 20. The ends of the hubs are cylindrical and reduced to form shoulders against which the edges of the washers loosely engage. These guard means effectually prevent oil and dust from entering the bearing of the wheels or the axle and at the same time permit free and independent movement of the roller-wheels.

The smoothing and packing means consists of a drag 23, having a smooth fiat under face and connected by ties or connections 24 at each side to the frame 3 of the roller means. Said drag may comprise longitudinal planks or strips 25, with cleats or cross-strips 26, on which are fastened hooks 27, to which the ties or hooked rods 24 are detachably connected by rings 29.

The connectors 24 are preferably rigid rods and are each pivotally connected at its forward end with the roller-frame, so as to permit the rear end to have a vertical movement only, while the links or rings 29 at the rear ends of the rods will permit the drag to vary its angle relatively to the plane of the rods.

This will permit the d rag to accommodate itself to the contour of the road-surface independently of the position of the rods vertically to the frame; but at the same time any movement. except to a limited extent, of the drag to one side or the other of the road or line of travel of the machine will be avoided. In this manner the drag will always be compelled to follow directly to the rear of the rollers.

The machine is used as follows: The rollerwheel frame 3 having been attached to the draft-truck 4, as by a hook 5 and the elastic connection 6, and the platform 8 having been properly loaded with stones or other weights, the machine is drawn along the surface of the road by means of a team or other traction means connected to the draft-truck. The wheels 1 have comparatively narrow flat-faced treads and are separate from one another, as above stated, so that the weight resting thereon will cause the wheels to be pressed into the surface of the road, penetrating into and through the loose material or dust at certain distance. The weight will be so proportioned that this distance will generally be about the distance to which it is desired to incorporate the oil with the roads surface. The effect of the wheels passing along in this manner is to compress the material directly beneath them and to partly displace the material into the spaces between the wheels, thereby kneading or mixing oil with the dust or sand. \Nhen these wheels have passed over the roadsurface, they leave the same with longitudinal ridges and furrows, and the drag 23, following the operation of said wheels, smooths out these ridges and furrows, thereby producing an even surface and at the same time further mixing the road material with the oil. The drag also presses the ridged material over and down upon the Hat depressions formed by the wheels, producing a compacting as well as smoothing effect.

The scraper 12 is adjusted to bear against a portion of the wheel periphery or tread which is rising when the wheels are rolling on the ground, so that the oil and dirt as they are scraped from the periphery of the wheel engage with and fall from the under side of the scraper.

What I claim is 1. In an oiled-road rollerand packer,aframe, a series of rollers mounted therein, rods pivotally secured at their forward ends to the frame so as to have free vertical movement, a drag and links for connecting the drag to the rear ends of said rods.

2. In an oiled-road roller and packer,a frame, a series of rollers mounted therein, a reversible scraper for the rollers consisting of an angle-iron the limbs of which are each perforated, supporting-arms, and bolts for engaging with said arms and with the holes of either of said limbs.
